A lot depends on your daytime obligations.

If you have a job during the weekdays, go to bed earlier that evening.

If you are un or self-employed and don’t need to be anywhere there is nothing inherently wrong with having a unique schedule. Some people do have a biorhythms that makes them more awake and focused at night. Sleepy around noon, evolved from our ancestors needing people who stay on watch at the fire.

Then there is also a long list of famous historic people who had very unique schedules with multiple smaller sleep times around the day.

The tricky part thou is when you suddenly do get daytime obligations and have to conform back to societal sleep standards.

Go to bed earlier than you did the previous night. Not necessarily at your goal time, but closer to your goal time than the previous night.

Staying up overnight and then all day until a good bedtime the next day will fuck you up more than it helps. I'm not so sure about trying to go to bed way before you get tired either. Regularity matters almost as much as quantity for sleep, so try to avoid totally bucking your cycle.

Booze has rarely helped me more than it harmed in terms of sleep, but there have been a few cases where it did, usually in medium amounts as a counter to bad coffee decisions. But it's a net negative overall and not to be trusted.

If one has woke up, then remain awake until one's natural cycle swings the other way: live in harmony with one's organism, & be healthier.

The cultural habit of arbitrarily-overriding one's natural cycle, because civilization proudly divorced nature, is idiotic in general, & especially for long-term-health.
